MZ1180/4型无心磨床是用切入法磨削气伐外圆专用磨床。适用于汽车行业大批大量生产,机床备有自动上下料机构。每一切入循环,同时磨削两只工件,砂轮与导轮主轴上分别安装两片砂轮及四片导轮(见图1)充分发挥宽砂轮无心磨床优点,生产率较高,粗磨跃进牌汽车排气伐,材料4Cr_9Si_2直径9毫米磨削长度109毫米,使用G60ZR_2AP砂轮,磨削余量0.23毫米,导轮转速为20转/分时,单件生产率为7.5秒,自动循环时间为15秒,其中磨削时间为8秒,上下料时间为7秒。精磨时,光洁度达▽_(9b),尺寸分散为0.005毫米(磨削一批220件),不圆度在0.005毫米以内,不直度为0.005毫米/全长,精度已能满足用户要求。
MZ1180 / 4 centerless grinding machine is cut into the method of grinding gas-cutting special grinding machine. Suitable for a large number of mass production in the automotive industry, the machine has automatic loading and unloading institutions. Each cut into the cycle, while grinding two workpieces, grinding wheel and guide wheel spindle were installed two wheels and four guide wheel (see Figure 1) give full play to wide grinder wheel centerless grinder advantages, high productivity, coarse grinding Yuejin vehicles Exhaust cutting, material 4Cr_9Si_2 Diameter 9 mm Grinding length 109 mm, G60ZR_2AP grinding wheel, grinding allowance 0.23 mm, guide wheel speed 20 rev / min, single production rate of 7.5 seconds, automatic cycle time of 15 seconds, The grinding time is 8 seconds, the loading and unloading time is 7 seconds. Precision grinding ▽ _ (9b), the size of the dispersion of 0.005 mm (grinding a batch of 220), non-rounding within 0.005 mm, not straightness of 0.005 mm / length, the accuracy has been able to meet user requirements .
